Product Details

If you're rebuilding the transmission on your Big Twin Harley-Davidson from 1991 through 2006, you'll need to replace the mainshaft seal. This 5-pack from Twin Power is designed to fit a wide range of these models, including popular bikes like the Road King, Electra Glide, and Heritage Softail. It's a direct replacement for the Harley-Davidson 12035A seal, ensuring a proper fit during your rebuild.

These seals are well-built to keep transmission fluid where it belongs, preventing leaks and ensuring smooth operation of your drivetrain. Replacing this seal is a straightforward part of many transmission service jobs, and having a reliable replacement makes the process smoother.
